Quote from the company about other materials - "While styrene or other sheet goods could possibly be used, it's unlikely that they'd produce anywhere near as crisp of an edge as is possible with our foil. And since damage the tool tip would likely occur quickly unless one were to exercise exceptionally conservative judgement when testing on any new materials, we have not tested the product on other materials since the sheer number of possible candidates and their varying mechanical properties are nearly unlimited."

*Tri-foil contains a central lead core. The same precautions should be used as when working with any lead bearing substance, even though very little actual contact with lead is expected due to the protective outer layer on each side.

Precautions to be taken in handling and storing:

Avoid inhalation of dust or fumes in concentrations above OSHA limits. Avoid accidental ingestion by using good personal hygiene practices. Wash thoroughly before eating or smoking if lead has been handled. Keep your work area clean and properly dispose of any unusable material.
